Description: | Fragment of copper-alloy plate, dark grey-green patina with slight traces of bronze disease. All edges are broken. On one face there is a narrow rib of slightly uneven, lumpy profile. The other face is flat and undecorated. The dimensions of the fragment are 31 mm (parallel to the rib) x 35 mm perpendicular to this, and 2.8 mm thick excluding the rib. It weighs 13.52g. Copper-alloy plate fragments with narrow ribs seem to have been cast from bronze (copper/tin) ingots mixed with lead, and then broken up for further use or for dispersal to other workers. They are extremely important for our knowledge of Late Bronze Age metalworking, and so far are only known from three other places; Isleham in Cambridgeshire, Guilsfield in Powys, and Roscommon in Ireland.
